If: The human brain has evolved throughout the eons from one mode of "thought" to a different mode, and

If: the last identified evolutionary step was somewhere between the present homo sapiens and some earlier form, e.g., homo erectus or afarensis, etc, and

If: Andrew Newberg is correct that there is an anatomically verifiable part of the brain that deals with "spiritual" matters, then

Hypothesis: The current human species has actually evolved into two separate subspecies, as yet unnamed and unidentified; each having a subtle difference in brain anatomy and physiology such that one species is capable of believing in the unbelievable and the other is not, the latter being the more recent adaptation.

xsomeday would explain why otherwise intelligent people are unable to apply the same laws of reason and logic to the subject of God and religion as they do to other areas of thought. Those of us who are fortunate enough to have descended from the line that no longer possesses the gene for the limiting cerebral structure, whatever that may be, would be free to pursue other interests instead of hopelessly trying to convince those whose brains are still carrying the maladaptive structure that they are incorrect.
